The BRESSER Venus 76/700 AZ reflecting telescope allows beginners to experience their very own stargazing hours quickly and easily. With the complete set, you are equipped with everything you need for your very own sky observations: an astronomical reflecting telescope with 76 mm aperture and 700 mm focal length, an azimuthal mount, a tripod as well as extensive accessories. And to guarantee a successful start in astronomy, the system is very easy to handle – the perfect first telescope for beginners! Established technology for your easy start – the telescope With this entry-level telescope, you will be able to admire the night sky through a classic Newtonian reflector. A little surprising for astronomy novices: with this particular type, you do not look in at the back of the telescope, but at the front and laterally. The advantage: even if the telescope aperture is directed vertically towards the sky, you can make your discoveries very comfortably. No need to bend down! In addition, the Newtonian reflector is very easy to use. The optics in this type of reflector telescopes are also impressive, because they are free of chromatic aberrations – resulting in good imaging properties at all times. A sharp image with good contrast – the Venus reflector telescope achieves this with its large focal ratio of about 1 to 9.2 (F/9.2 – calculated from 76 mm aperture and 700 mm focal length). Thanks to its long focal length, the telescope for beginners shows you the Moon, Sun, planets, open star clusters as well as globular clusters in a particularly impressive way. And all this at a magnification of up to 150x in really sharp images! Technically, you can magnify even higher – theoretically up to 525x while using the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. Of course, how much you can magnify depends not only on the resolving power of your telescope. The air turbulence in the atmosphere (seeing conditions) also plays an important role. Note for nature lovers: If you choose a Newtonian telescope like the Venus reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. A good foundation for a successful start – mount and tripod The height-adjustable aluminium tripod and the azimuthal mount provide a firm footing and easy celestial navigation. Especially the azimuthal mount makes life easy for beginners, because it is very user-friendly: just like a typical photo tripod, you turn the telescope by hand to the left and right, up and down. This way, your favourite celestial objects quickly appear in your field of vision. Handy: to ensure that your astronomy accessories are always within reach, there is a storage plate between the tripod legs. Everything that goes with it – the accessories Out of the box straight to the fun of observing – with the complete astronomy set, you are quickly on your way to discovering the universe. The LED viewfinder helps you keep an eye on the sky. You just mount the direction finder parallel to the actual telescope and it projects a red dot onto a small ground-glass screen. This then appears to be hovering in front of the sky when you look through the viewfinder. And it does so at exactly the same spot that your telescope is pointed at. This way, the LED finder helps you to align the reflector telescope precisely and to find the celestial objects more easily. When it comes to the level of detail in your observations, the Venus beginner's reflector telescope gives you a choice: the two included eyepieces (4 mm and 20 mm) allow you two different magnifications. You want to get an even closer look? Then simply triple the magnification of the eyepieces with the 3x Barlow lens. In addition, the socket diameter of 31.7 mm (1.25 inch) complies with an international and manufacturer-independent standard. So you can easily expand your set – and with it your astronomical horizon. If you want to observe fascinating sights not only at night but also during the day, simply grab the solar filter. With it, you can safely admire spots and granulation on our nearest star – the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! A new hobby leads to new impressions – and naturally you want to capture and share those. Therefore, you can easily use your mobile phone for your first steps into astrophotograpy with the smartphone adapter. Perfect for great snapshots of the Moon or the Sun, for example. Look forward to exciting astronomical discoveries by day and night – with the BRESSER Venus 76/700 AZ reflector telescope. FEATURES Reflector telescope for beginners with 76 mm aperture and 700 mm focal length Reflector type Newton Good for observing Sun, Moon, planets and star clusters Height-adjustable tripod with azimuthal mount Easy to use even by beginners Focal ratio F/9.2, thus sharp image and good contrast Two eyepieces and a Barlow lens with 31.7 mm (1.25 inch) sockets for different magnifications Safe solar observation with the included solar filter First steps into astrophotography with included smartphone camera adapter SCOPE OF DELIVERY Refractor telescope Aluminium tripod Azimuthal mount Eyepieces: 4 mm and 20 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual

Unpack, set up, enjoy – with this complete telescope set you will soon begin your first exploration of the night sky. All the equipment for your new, exciting hobby is already included: the lens telescope with 70 mm aperture and 900 mm focal length, the equatorial mount, the tripod and a wide range of accessories for astronomical observations. Ideal for beginners: the system is very easy to handle and can even be used by children. Well-proven design for an easy beginning – the telescope With this set you'll start your voyage of discovery to the stars with a classic refracting telescope, a so-called achromatic refractor of the Fraunhofer type. The advantage of this particular design: even beginners as well as children can use it with ease. In addition, the Lyra refracting telescope impresses with good imaging properties due to its modern, precisely coated optics. If you compare this entry-level telescope to a corresponding astronomical telescope with a 60 mm aperture, you will notice: With its 70 mm aperture, the Lyra already collects 36 % more light. It also offers better resolution. In addition, 70 mm aperture and 900 mm focal length result in a very large focal ratio (ratio of aperture to focal length) of about 1 to 12.9 (F/12.9). The impressive result: a very sharp image with good contrast. Enjoy the view of our natural satellite, the Moon. Or take a look at the planets. Even the famous Pleiades sparkle captivatingly in your field of view. For the long focal length makes the telescope a specialist for observing the Moon, Sun, planets and open as well as globular clusters. And how big will these eye-catchers of the sky appear? Thanks to the 70 mm aperture, the resolution allows magnifications of up to 140x with really sharp images. Technically, much more would be possible – theoretically up to 675x using the included accessories. However, then the image sharpness could slowly decrease with increasing magnification. Of course – as with everything in astronomy – the prevailing conditions also play a role: So, how much you can actually magnify is determined not only by your telescope's performance but also by the air turbulence in the atmosphere (seeing conditions). Perfect foundation for your glimpse into space – mount and tripod Once you have found the ideal location for your astronomical telescope, you can quickly start exploring the sky. Simply mount the tube with the equatorial mount on the height-adjustable aluminium tripod. This special type of mount has the advantage of particularly convenient tracking: for this purpose, an axis is aligned parallel to the Earth's axis by pointing it approximately at Polaris during the so-called "alignment". Afterwards, the movement of the celestial bodies can be conveniently compensated for on this one axis rather than on both at the same time, as is the case with an azimuthal mount. In addition, the two flexible shafts with fine adjustment ensure the very precise and comfortable adjustment and tracking of the entry-level telescope. Always the right accessories at hand: the storage plate between the tripod legs provides space for eyepieces, barlow lens, solar filter etc.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! All-round equipment for astronomy newbies – the accessories Moon, planets or the Sun – with the extensive accessories you will get the best out of your astronomical telescope for any observation object. But initially, the LED viewfinder helps you find the nocturnal celestial bodies in the first place. To do this, the direction finder is installed and aligned parallel to the actual telescope. When you then look through it, a small red dot appears to hover in front of the sky. It shows you the spot at which the telescope is pointed. In this way, you precisely align the tube and easily find your objects before you gaze at them through the higher magnification of the telescope. Change of perspective for stargazers: using the two eyepieces you achieve different magnifications. They can be switched easily: With their standard socket diameter of 1.25 inches (31.7 mm), they are simply inserted into the eyepiece focuser of the entry-level telescope. Looking for even more detail? Then grab the 3x barlow lens and triple the magnification of the eyepieces. Comfortable observation at all times: a 90-degree star diagonal mirror is included. So, even if the telescope points vertically upwards into the sky, you can still look in comfortably from the side. For exciting discoveries during the day simply attach the safe solar filter to the telescope’s aperture. This way you can take a closer look at our own star and marvel at sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Take the plunge into the fascinating world of astrophotography with the smartphone adapter. It allows you to use your smartphone as a camera on the telescope – and easily take exciting snapshots of your favourite celestial bodies such as the Moon or the Sun. FEATURES Beginner’s lens telescope with 70 mm aperture and 900 mm focal length Achromatic refractor type Fraunhofer Well suited for observing the Sun, Moon, planets and star clusters Height-adjustable tripod with equatorial EQ3 mount Sensitive adjustment through flexible shafts and fine adjustment in both axes Easy to use, very suitable for beginners and children Focal ratio F/12.9, thus very sharp image and high contrast 1.25 inch (31.7 mm) eyepiece focuser Two eyepieces and one barlow lens with 1.25 inch (31.7 mm) extension tubes for different magnifications Safe solar observation with the included solar filter First steps in astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25 inch sockets) Barlow lens, 3x (1.25 inch socket) Star diagonal mirror LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual

Set off in search of your own fascinating discoveries at the night sky. This starter set comes with everything you need for your first astronomical observations: reflector telescope with 130 mm aperture and 650 mm focal length, equatorial mount, tripod and comprehensive astronomical accessories. The system is very easy to use and extremely versatile. It is suitable for observing the Moon, the Sun and the planets as well as star clusters and gas nebulae. Ideal for your easy start in sky observation! Astro all-rounder for beginners - the telescope The astronomical telescope is a classic reflector telescope, a so-called Newtonian reflector. One characteristic of this particular type: They are designed to look in at the front and from the side instead of the rear. Thus, the observation position always remains comfortable, even when the tube is pointed vertically into the sky. Once familiar with it, the telescope is also very easy to use. These reflector telescopes also have one important advantage regarding their optics: they are free of chromatic aberrations and thus offer good imaging properties. With its 130 mm aperture, this entry-level telescope already collects a lot of light from celestial objects. In addition, 130 mm aperture and 650 mm focal length result in a short focal ratio (ratio of aperture to focal length) of 1 to 5 (F/5). This allows you to marvel at a bright image through this fast telescope. It also allows for high magnifications, making the beginner's telescope a flexible all-rounder for sky observing. Enjoy the full range of astronomical highlights: At low to medium magnification, take in open and globular clusters such as M13 in the constellation Hercules. Or you can admire gas nebulae such as the famous Orion Nebula M42. At high magnifications, on the other hand, observing the planets or details on the Moon becomes an absolute pleasure. The 130 mm aperture offers a resolution which allows you to admire your favourite celestial objects in sharp images at magnifications of up to about 260x. Technically, even more is possible - theoretically up to 487.5x with the included accessories. However, the image sharpness can then slowly decrease with increasing magnification. Nevertheless, how much you can really magnify, depends not only on your telescope. The air turbulence in the atmosphere (seeing conditions) is also always an important factor in your astronomical observations. Please note that reflecting telescopes of the "Newton" type always produce images both laterally reversed and upside down. This does not matter for astronomical observations, which is why these telescopes are very well suited for these purposes. For nature and landscape observations during the day, however, this characteristic is disruptive. Therefore, we recommend the BRESSER refracting telescopes for this application. User-friendly and stable - mount and tripod Have you found the perfect place for your observations? Then just attach the telescope to the equatorial mount and the height-adjustable aluminium tripod. The advantage of this type of mount: unlike azimuthal models, the movement of the celestial bodies has to be counterbalanced on just one axis. For this purpose, one axis is aligned parallel to the Earth's axis by pointing it approximately at the polar star. Adjustment and tracking of the telescope is particularly precise and comfortable via the two flexible shafts with fine adjustment. And your accessories stay always within reach on the storage plate attached to the tripod.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Complete astronomy starter package - the accessories Unpack and get started straight away - the beginner's telescope comes with lots of accessories. The LED viewfinder enables you to navigate the night sky with ease. This direction finder is installed on the telescope and projects a red dot onto a small ground-glass screen. When you look through it, the red dot appears to be floating at the exact location in the sky to which the telescope is pointed. Thus, the LED viewfinder allows you to easily find celestial objects and accurately align the telescope. Different perspectives of the night sky: With the two eyepieces included, you are able to view astronomical objects at different magnifications. With the standard 31.7 mm (1.25 inch) diameter sockets, they are simply inserted into the telescope's focuser. Do you want an even more detailed image? Then the 3x barlow lens can triple the magnification. However, during the day taking a look at the sky is also worthwhile: with the solar filter you can safely observe sunspots and granulation on our very own star. CAUTION: Never point the telescope at the Sun without the solar filter! Whether Sun, Moon, planets or deep sky objects - with the smartphone adapter you can capture your most fascinating moments on intriguing snapshots.

Take a closer look at the wonders of the universe. This complete telescope set for beginners contains everything you need for your new hobby: a refractor telescope with 80 mm aperture and 900 mm focal length, an equatorial mount, a tripod and a wide range of accessories for astronomical observations. The system is very easy to handle and can even be used by children. Simply unpack, set up and get started – you will be amazed at what you will discover! Easy start with user-friendly classic – the telescope The astronomical telescope is a traditional lens telescope, a so-called Fraunhofer achromatic refractor. The advantage of this established telescope type: even beginners and children find it easy to operate. In addition, the BRESSER Quasar scores points for its modern, precisely coated optics with good imaging properties. A direct comparison shows: With its 80 mm aperture, this telescope already collects 30 % more light than a 70 mm telescope and the resolving power is better as well. This means that you can already marvel at some of the details on Mars through the Quasar. In addition, 80 mm aperture and 900 mm focal length mean a large focal ratio (ratio of the aperture to the focal length) of about 1 to 11.3 (F/11.3). The result: a very sharp image with good contrast. Due to its long focal length the entry-level telescope is a specialist when it comes to observing the moon, sun, planets, open star clusters and globular clusters. But you can also take a look at many gas nebulae through this telescope, such as the famous Orion Nebula M42 or the Ring Nebula M57. How big will you see the fascinating celestial bodies? The 80 mm aperture achieves a resolving power that easily allows magnifications of up to about 160x with really sharp images. Technically, much more is possible, theoretically up to 675x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition to the equipment, the conditions play a role as well: the air turbulence in the atmosphere (seeing conditions) also determines how much you are able to magnify. Sturdy base for your easy astro-beginning – mount and tripod Found the perfect spot for your nocturnal explorations? Then install the telescope effortlessly on the height-adjustable aluminium tripod using the equatorial mount. The advantage of this type of mount: unlike the azimuthal models, you compensate for the movement of the celestial bodies along just one axis instead of two. To do this, you align one axis parallel to the Earth's axis, which is called "alignment". This is easily done by pointing it approximately to Polaris. The beginner's telescope also comes with two flexible shafts with a fine adjustment, which simplify the movement of the axes. They make adjusting and tracking very precise and comfortable. Handy storage: On a plate between the tripod legs, you can store your accessories within easy reach.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! The complete package for your sky observations – the accessories The extensive astronomy accessories including a safe solar filter enable you to immediately direct your gaze through the lens telescope to the sky – day and night. When observing at night, the LED viewfinder helps you find your way around: just install it parallel on the telescope, adjust it and use it to align and locate celestial objects. When you look through it, the red dot projected onto a ground-glass screen inside appears to hover in front of the sky. It shows you the spot to which the tube is pointing. This allows you to navigate easily before taking a closer look with the telescope's high magnification. Different perspectives of your astronomical discoveries are made possible by the two eyepieces, which enable different magnifications. With their sockets, which have a standard diameter of 1.25 inch (31.7 mm), they are simply inserted into the telescope's focuser. You want to see even more details? Then triple the magnification of the eyepieces with the 3x barlow lens. Always comfortable while observing the stars – for this purpose the 90-degree star diagonal mirror is included. That way you always enjoy a pleasant view into the telescope. Even if it is pointed upwards into the sky, you can comfortably look in from the side. Discover the beauty of our own star: Using the telescope in combination with the solar filter you can safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Have you always been fascinated by astrophotography? Then your smartphone camera and the smartphone adapter will get you started. This way you'll quickly enjoy your first own photos e. g. of the moon or the sun.
